ZurichJS Pro Meetup: H(a)unt the gaps in your Apps

JSON is everywhere: in API responses, config files, hard-coded data, and everything in between. Yet we rarely validate our JSON properly. Working with unstructured JSON often leads to subtle bugs that are hard to debug and even harder to prevent.

But here's the good news: JSON has a secret weapon: a schema.

In this talk, I’ll introduce JSON Schema and show how you can use it to:

Define clear, reusable data structures
Validate your JSON data
Share schemas across apps or teams as a contract
Keep things robust without adding too much overhead
Whether you're building a complex app or just trying to keep your config files sane, this talk will help you level up your JSON game with just the right amount of structure.

Do you lie awake at night wondering if your app could be compromised? Have you ever questioned how safe the apps you ship using the React ecosystem really are? Do you know to which types of vulnerabilities are you exposed when those security systems are not in place? In this talk, we'll explore a guinea pig web app to explore the threats that could easily affect your own projects.

Video is everywhere on the web, from hero banners to product videos to full-blown streaming. However, while Lighthouse reports issues related to images, scripts, and more, it doesn't really address video performance. That means streaming can suffer for end users, resulting in buffering and slow starts, while businesses incur huge data transfer costs due to unoptimized delivery.

In this talk, we'll explore some quick wins every developer should know: optimizing videos size and format, optimizing streaming for every device and network, and different video loading strategies to improve performance. You'll leave with a toolkit to make your videos load faster, play smoother, and feel as polished as the rest of your app, closing a significant gap that performance audits often overlook.
